Psychology of the Heart
Mystics have invariably affirmed that the seat of God, within, is the heart. The heart is then the centre on which one must meditate. The heart is the emotional centre. It is also the centre of physiological blood circulation to which all blood flows, and out of which it flows to all parts of the body. The seat of life, for man, is the heart. For the person who seeks to know the secret of life, meditation on the functions of the heart is important.
Most persons are also diseased in the heart. Heart troubles are mainly the effect of strains on the heart affections. Therefore not only is it the centre of circulatory processes of the blood, which it purifies and sends out, it appears to be the centre which is closely linked with affections, and it is this aspect that seems to be important for a proper and fuller understanding of the heart. The heart is closely linked with the nervous system, the autonomous nervous system, and along with the glands we have an integrated autonomous activity of both the afferent and efferent functions.
In meditation what is usually done is that one imagines at the region of the heart a light, a form of God, or an akasa (dahara) and so seeks to see it internally, that is to say, as one would see it in a dream. This, normally, is possible for most imaginative minds, but is almost next to impossible to others. Meditation on any form-a form projected from outside into this internal perception'is finally valueless. The experience of the inner Self seems, ultimately, to be beyond even internal vision. The sense of being is what one may at best be able to feel. It is the peace of the heart.
The heart is connected, we said, with the other circulatory systems of the nerves too, if we may so speak about this nervous system. The important centres of the nervous system are the spinal cord and the brain with all its several divisions: the cerebrum, cerebellum, medulla and so on. This connection with the nervous system is almost the connection with the 'thought' element so to speak, or the mind. At the present state of our knowledge we may not identify the two, but there is no doubt that at the physical level the thought manifests itself in the form of nervous flow and feeling in terms of blood and glandular flow (flow of secretions of glands).
